Ineffective monitoring of residual chlorine in reverse osmosis equipmentIf the pump for adding NaHSO3 fails or the liquid fails, or the membrane is damaged by residual chlorine when the activated carbon is saturated.Improper cleaning and incorrect cleaning methods lead to damage of membrane performa Read More

White or black suspended particles appear in pure water Solution: This is because the pipeline is contaminated, resulting in the growth of bacteria. This situation should be dissolved caustic soda into the precision filter, operate the regulating valve to close the waste water, pure water open to a Read More

How should the reverse osmosis equipment be operated for the first time?The air in the pipeline will be driven away by low pressure and low flow, only when the air in the pipeline does not exist can the equipment operate normally. First of all, the pressure should be kept between 0.2~0.4MPa. When us Read More

Currently in water filtration, reverse osmosis membranes and nanofiltration membranes are the most commonly used membrane elements, but many users have a vague understanding of reverse osmosis membranes and nanofiltration membranes. Today Jun Xin will introduce to you what the differences between RO and NF membranes are, as well as the commonalities and differences. Read More

The microstructure and filtration mechanism of reverse osmosis (RO) membranes, the most efficient filter membranes for contaminant retention, has been a hot topic of research. So, is an RO membrane a porous or non-porous membrane? The knowledge and answer to this question will have a direct impact on the understanding of the filtration mechanism of RO membranes. The answer to this question is changing with the advancement of technology and the deeper analysis of the microstructure of RO membranes. Read More

Reverse osmosis technology is currently the highest of all water production technologies mastered by mankind, through reverse osmosis components to improve the purity of water, cleanliness of almost 100%, to remove impurities and salt contained in the water. In the selection of reverse osmosis equipment, we are mainly concerned with two indicators: the desalination rate and the recovery rate, the former determines the quality of the water produced and the latter determines the utilisation rate of the water.
